Bypassing a Brinks with a bra underwire

Thanks mate! My gf was complaining about the underwire while I was picking, and I figured I'd try it out.

I'd say that they're thinner than or as thick as my Bogota Ti flats, so they should have little issue entering a keyway as demonstrated, but I would recommend using another tool as a tension wrench.

Also, unless one owns a dremel or other machining tool, turning it from a flat curved wire into a pick-shape would be nigh-impossible, as the ends are flat and rectangular. So not great for picking, but as you can see, an effective shim!
